core: allow having a list of "cmake" candidates
Add the BR2_CMAKE_CANDIDATES variable, containing a list of candidates to check and use as BR2_CMAKE, if possible. This allows using "cmake3" on CentOS 7, whose default cmake corresponds to version 2.8.12. Example: $ make BR2_CMAKE_CANDIDATES="cmake cmake3" Signed-off-by: Carlos Santos <casantos@datacom.ind.br> Reviewed-by: "Yann E.
